Foundries and sand producers invest significant resources in quality control of their sand systems, with extensive testing done to maintain consistency. As a result, FS from an individual facility will generally be very consistent in composition, which is an advantage for most end use appliions.
Sand casting: Casting method characterized by the use of sand as the mold material. Molding sand is typically mixed with a bonding agent such as clay and moistened with water or other liquid to create suitable mold strength and plasticity (See green sand). The mold cavity is formed by compacting sand into a mold box (or flask) around the pattern.
· Since foundry sand does not need to be processed at all for reuse, the structure with foundry sand filter layer has the lowest calculated emission. When a filter cloth is used, a thicker separation layer of crushed rock should be applied to satisfy the frost resistance requirements, which increase the emissions significantly from processing of the crushed rock.
